I installed the SiriusXM online app for my Evo and have noticed that it will only play content if I'm on wi-fi. When on 3G it keeps saying there is no data connection, but the channel content will update. I uninstalled/reinstalled, and the glitch persists. Does this mean that the app will only play on wi-fi? If so, this sucks, because I was hoping to use it on the drive to work to listen to a channel that's not available on the radio (Viva).
